CryoSTUCK® – Cryo Labels for Frozen Vials

The challenge of labeling frozen vials

Labeling frozen vials is a significant challenge for many bio-pharma research labs, cell banks, biorepositories and other laboratories involved in the biopreservation and biobanking of samples in liquid nitrogen and ultra-low temperature freezers. Simultaneously, vials containing biological materials cannot be thawed due to the temperature sensitivity of their content. In most cases, the re-labeling of these vials has to be done below -70°C so as not to compromise the viability of the frozen cells.

The solution to labeling frozen vials

To solve this challenge, we developed CryoSTUCK®, a unique product line of cryogenic labels and Tapes that can stick to already frozen vials, and other containers (as low as -80°C). They can be successfully applied to frozen containers and then stored in liquid nitrogen tanks (-196°C) or -80°C freezers for further preservation. Our CryoSTUCK tapes are available in clear and a range of colors, for easy identification, and color coding.

Over-labeling legacy vials

Blackout CryoSTUCK have a unique opaque design, perfect for over labeling legacy vials that cannot be thawed and already have a label applied. These opaque “cover-up” cryo labels are designed to completely obscure existing labels and conceal their obsolete or outdated information. They are ideal for re-labeling frozen vials when removal of the existing label is not possible.

Laminating existing labels

Our Clear CryoSTUCK labels can also be used to over-label vials and tubes, but their transparent design will not obscure the underlying label. Ideal for laminating existing labels, these robust labels will provide an extra layer of protection, safeguarding your printed information from chemicals, abrasion, and extreme temperatures.

Application of labels

For proper functionality on vials and tubes, thermal-transfer CryoSTUCK labels must have an overlap of at least 0.25”. Once applied with clear overlap, they are able to withstand multiple freeze-thaw cycles, dry-ice transportation, and exposure to water/condensation.

Printing CryoSTUCK labels

Thermal-transfer CryoSTUCK can be printed using standard brands of barcode printers such as Zebra, cab, SATO, Printronix, Intermec, Datamax O’Neil, Citizen, Cognitive, Brady (selected models), and GA International’s new Cody-300. Our L2FS and L2FC label classes require our XAR-class of thermal-transfer ribbon, while we recommend our RR-class of resin ribbons for the AEA and AHA label classes. They also accept writing with permanent markers such as our Science-Marker™ – alcohol and water-resistant cryogenic marker.

We also offer our all new Laser CryoSTUCK labels, that will adhere to already frozen surfaces without the need of an overlap, and can be printed using your desktop laser printer (HP, Brother, Samsung). We provide free online MS Word templates for quick template set-up, and easy printing.

Industries Served

These unique cryogenic labels can provide an ideal solution to many laboratories involved in long-term biopreservation of tissue samples such as cord blood banks, cell banks, tissue banks, seed banks, sperm banks and other cryogenic storage facilities in the biomedical and veterinary fields.
